WASHINGTON >> A retired police officer in the nation’s capital was convicted Monday of lying to authorities about leaking confidential information to the leader of the Proud Boys extremist group.

U.S. District Judge Amy Berman Jackson convicted former Metropolitan Police Department Lt. Shane Lamond of obstructing justice and making false statements after a trial without a jury.

Sentencing was scheduled for April 3 after Lamond’s conviction on all four counts.

Lamond was charged with leaking information to then-Proud Boys national chair Enrique Tarrio, who was under investigation in the burning of a Black Lives Matter banner.

Lamond testified at his bench trial that he never provided Tarrio with sensitive police information. Tarrio, who testified as a witness for Lamond’s defense, said he did not confess to Lamond about burning the banner and did not receive any confidential information from him.

But the judge did not find either man’s testimony to be credible. Jackson said the evidence indicated that Lamond was not using Tarrio as a source after the banner burning.

“It was the other way around,” she said.

The judge said the string of messages that Lamond and Tarrio exchanged over the course of months showed a pattern: “Lamond and Tarrio talk, and Tarrio immediately disseminates what he learns,” she said.
